Parts for your 2021 Toyota Prius-Fuel pump

2021 Toyota Prius fuel pump — what it is and how to look after it

Based on Toyota’s technical literature for the 2ZR-FXE engine (New Car Features and Repair Manual – SFI/Fuel System) and Toyota’s Electronic Parts Catalogue, the 2021 Toyota Prius is fitted with an electric, in-tank low‑pressure fuel pump. It’s supplied as a “fuel suction with pump and gauge” module inside the tank, not a mechanical pump on the engine. Industry bulletins from Denso and Toyota on low‑pressure fuel pumps also describe this style of in‑tank electric pump used across late‑model Toyota hybrids.

On the 2021 Prius, the fuel pump’s main job is simple: draw petrol from the tank and deliver it to the injectors at a steady, modest pressure. Because the Prius uses port fuel injection (not high‑pressure direct injection), it only needs a reliable low‑pressure supply
